I had one done with the Remicade a few months ago, and that showed that I had the antibody and I was unable to take that anymore. So on to the Imurian I went, and was sent for another Prometheus test about a week ago and the nurse called and told me that it is showing a reading of 20 and it should be closer to 400? I asked her what that meant & does that mean the same thing is happening with the antibody? She told me she would get with the dr and get back to me.

That was Fri afternoon and sooooooo now I will have to wait til Tues for answers.

Was wondering if anyone had any insight on this ? Any help is greatly appreciated.

Diagnosed 4 years ago. been a helluva ride since. If there is a side issue to this dd I can find it. I suffer with Pyoderma Gangrosum and horriffic mouth ulcers that get to the point I can't open my jaws. Last one was nice enough to create a fistula and add to my list of fun things to deal with.

Been on all kinds a things, currently on Imuran 50 mgs and it at least give me some confidence in leaving my home.

The last Prometheus test you had likely was checking to see what level of Imuran you have in your blood. Some doctors use that test to make sure that a patient has achieved a therapeutic level of the medication on the dosage they are taking. Other times the test might be ordered if the doctor suspects that a patient has too much Imuran in the system. Hope this helps.
